Functional Features:

Dual-Channel Monitoring: Independently processes signals from two sensors for simultaneous parameter tracking.
Signal Conditioning: Converts raw sensor data into standardized units (e.g., g, mm/s) for accurate analysis.
Programmable Alarms: User-configurable thresholds for overspeed, underspeed, and vibration levels trigger alerts.
Self-Diagnostics: Continuously monitors module health and alerts users to potential issues via LED indicators (OK, Alarm, Trip).
Seamless Integration: Works with the 1701 FieldMonitor™ system rack and System 1 software for centralized data logging and trending.
Flexible Configuration: Supports customization of measurement ranges, alarm thresholds, and output signals.
High-Speed Data Acquisition: Captures transient vibration events with sampling rates up to 100 kHz.

Application Scenarios:

Turbomachinery: Monitors turbine and generator vibrations to detect imbalance, misalignment, or resonance.
Compressors: Tracks pressure pulsations and vibration in centrifugal and reciprocating compressors to prevent cavitation or seal failures.
Pumps: Detects vibration anomalies in pumps to avoid mechanical damage or cavitation.
Motors: Safeguards electric motors from excessive vibration during startup or load changes.
Power Generation: Ensures safe operation of steam turbines and boilers by monitoring vibration and process parameters.
Marine Propulsion: Protects ship propulsion systems by detecting vibration-related faults.
Chemical Processing: Monitors reactor vibrations for stable and efficient operation.
Building Automation: Tracks vibration in HVAC systems or elevators to ensure facility reliability.
